The Minoan eruption of Santorini was a large-magnitude natural event. However, in terms of scale it ranks smaller in erupted volume and eruptive intensity than the historical eruption of Tambora in 1815 AD, and smaller in sulphur emission and, by inference, climatic effects than both the Tambora and Mt. Pinatubo, 1991, eruptions.
From Wikipedia, the free encyclopedia. For the band, see Linea Aspera (band) . The linea aspera (Latin: rough line) is a ridge of roughened surface on the posterior surface of the femur, to which are attached muscles and intermuscular septum.Its margins diverge above and below. number of muscles attach to the linea aspera: 1  From the medial lip of the linea aspera and its prolongations above and below, the vastus medialis originates. 2  From the lateral lip and its upward prolongation, the vastus lateralis takes origin.
Most skeletal muscles are attached to bone or cartilage by a tendon, aponeurosis, or by direct attachment. Tendon attachment is by far the most important and is present wherever the point of insertion is distant or the muscle must exert its forces of contraction across a joint.HE MUSCLE FIBER. The units of skeletal muscle are the muscle fibers or muscle cells, each having many hundreds of nuclei that are slender and oval. They are oriented parallel to the length of the fiber and lie peripherally in the zone immediately within the cell membrane or sarcolemma.
